Integration and verification
Validation and production releaseThe successful Embedded Software Engineer will work closely with hardware, data, and product engineers to deliver robust, secure, and power-efficient sensing platforms operating in demanding real-world environments.

Key Responsibilities

Architect and develop low-power embedded firmware (C/C++) for sensor platforms
Design for ultra-low power consumption in battery-operated and remote systems
Implement sensor data acquisition and processing pipelines (e.g. MEMS microphones, accelerometers and other environmental sensors)
Develop and optimise RF communications systems, particularly:
LoRa or similar LPWAN technologies
Mesh networking architectures
Implement secure communications including encryption, authentication and secure boot mechanisms
Develop machine learning-enabled acoustic detection and classification systems:
Data pre-processing and feature extraction
Deployment of optimised ML models on constrained embedded devicesEssential Experience

Significant experience in embedded C/C++ development
Strong experience across the full product lifecycle (concept → production)
Proven expertise designing for low-power embedded systems
Experience with sensor data acquisition and real-time signal processing
Strong RF communications experience, particularly LoRa or comparable technologies
Experience implementing mesh networking protocols
Solid understanding of embedded security (encryption, authentication, secure firmware updates)
Strong debugging and hardware bring-up skillsHighly Desirable

Machine learning for acoustic detection/classification
Experience with MEMS microphone-based systems
Wind/ambient noise mitigation design (hardware and software)
Secure OTA update mechanisms
Experience in a start-up or high-growth environmentIf you're a Senior Embedded Software Engineer looking to build intelligent, low-power sensing systems from the ground up - KO2 would be delighted to discuss this opportunity with you

New Robotics Employers to Watch in 2026: UK and Global Companies Transforming Automation Careers

Robotics is moving rapidly from factory floors into healthcare, logistics, agriculture, autonomous systems, and consumer products. As automation becomes embedded in everyday life, companies are investing in robots that operate alongside humans, analyse environments in real time, and learn from data. In 2026, demand for robotics engineers, software developers, system integrators, and AI specialists continues to surge. For professionals exploring opportunities on www.RoboticsJobs.co.uk , understanding the employers that are scaling, winning contracts, securing investment, or expanding into the UK market is crucial. This article highlights top robotics employers to watch in 2026, spanning innovative startups, high‑growth scale‑ups, and established global technology leaders with strong UK presence.

How Many Robotics Tools Do You Need to Know to Get a Robotics Job?

If you’re pursuing a career in robotics, it can feel like the list of tools you should learn never ends. One job advert asks for ROS, another mentions Gazebo, another wants experience with Python, Linux, C++, RobotStudio, MATLAB/Simulink, perception stacks, control frameworks, real-time OS, vision libraries — and that’s just scratching the surface. With so many frameworks, languages and platforms, it’s no wonder robotics job seekers feel overwhelmed. But here’s the honest truth most recruiters won’t say explicitly: 👉 They don’t hire you because you know every tool — they hire you because you can apply the right tools to solve real robotics problems reliably and explain your reasoning clearly. Tools matter — but only in service of outcomes. So the real question isn’t how many tools you should know, but which tools you should master and why. For most robotics roles, the answer is significantly fewer — and far more focused — than you might assume. This article breaks down what employers really expect, which tools are core, which are role-specific, and how to focus your learning so you look capable, confident, and ready to contribute from day one.

What Hiring Managers Look for First in Robotics Job Applications (UK Guide)

Robotics is one of the most dynamic, interdisciplinary fields in technology — blending mechanical systems, embedded software, controls, perception (AI/vision), modelling, simulation and systems integration. Hiring managers in this space are highly selective because robotics teams need people who can solve real-world problems under constraints, work across disciplines, and deliver safe, reliable systems. And here’s the reality: hiring managers do not read every word of your CV. Like in many tech domains, they scan quickly — often forming a judgement in the first 10–20 seconds. In robotics, those first signals are especially important because the work is complex and there’s a wide range of candidate backgrounds. This guide unpacks exactly what hiring managers look for first in robotics applications and how to optimise your CV, portfolio and cover letter so you stand out in the UK market.
